Age-related Changes in Maximum Pelvic Anteversion and Retroversion Angles Measured in the Sitting Position

Area of Science:

• Biomechanics
• Gerontology
• Human Movement Science

Background:

• Pelvic mobility is crucial for functional activities.
• Age-related changes in musculoskeletal structures can affect joint range of motion.
• Understanding age-related pelvic motion is important for assessing functional limitations.

Purpose of the Study:

• To examine the correlation between age and pelvic range of motion in healthy adults.
• To quantify maximum pelvic anteversion and retroversion angles across different age groups.
• To determine how age influences sitting pelvic mobility.

Main Methods:

• 132 healthy volunteers (20-79 years) were grouped by age.
• Maximum pelvic anteversion and retroversion angles were measured using a goniometer.
• Measurements were taken in a sitting position with unrestricted knee movement.

Main Results:

• Age significantly affected maximum pelvic anteversion, retroversion, and overall pelvic range of motion.
• A significant negative correlation was found between age and pelvic anteversion.
• Pelvic range of motion and retroversion also showed significant correlations with increasing age.

Conclusions:

• Age is a significant factor influencing pelvic anteversion, retroversion, and range of motion.
• Maximum pelvic anteversion and pelvic range of motion demonstrate the most pronounced age-related decline.
• These findings suggest age-related changes in spinal and hip structures impact sitting pelvic mobility.
